Are There AI Platforms That Allow Customisation of Agents to Fit a Company's Brand Voice?
The short answer is Yes. But not all "customization" is created equal.
If you ask a standard AI chatbot to write an email, it will usually sound like... well, a robot. It tends to be overly polite, uses generic phrases like "I hope this email finds you well," and lacks the specific spark that makes your brand unique.
For a business, this is a problem. You have spent years defining your brand voice—whether it's the professional authority of a law firm or the quirky energy of a lifestyle startup. You cannot afford to lose that identity just because you are automating.
If you are looking for platforms that allow you to "train" an agent to speak like you, there are three main categories of tools available today. Here is how they compare.
1. The "Manual" Prompting Tools (e.g., ChatGPT, Jasper)
These are the general-purpose writing assistants.
How Customization Works: You have to "tell" the AI who to be every single time you use it. You must type: "Act as a senior copywriter and write this in a witty tone."
The Verdict: Great for one-off tasks like writing a blog post. Terrible for automation.
The Problem: You cannot easily "save" this voice for an automated website chatbot. If a customer chats with it, the AI reverts to its default, robotic personality. It has no persistent memory of your brand guidelines.
2. The "Toggle" Support Bots (e.g., Intercom Fin, Zendesk)
These are established customer support platforms that have added AI features.
How Customization Works: They often give you a simple slider or toggle. You can choose between "Formal" or "Casual," or perhaps "Short" vs. "Long."
The Verdict: Good for basic support, but too rigid for branding.
The Problem: Your brand is more complex than just "Formal" or "Casual." A toggle cannot capture the nuance of your specific vocabulary, your forbidden words, or your unique empathy style. You are stuck with their pre-set definitions of what "Professional" sounds like.
3. The "Deep Persona" Platforms (e.g., AiSentr)
This is the newest category: Agentic AI Platforms. These tools are built specifically to create digital employees that "live" your brand 24/7.
How Customization Works: Instead of a simple toggle, you provide a "System Persona." This is a set of permanent instructions that governs the agent's behavior.
Example: You can upload your 20-page "Brand Voice PDF" and tell the agent: "You are Sarah, a helpful technical guide. Never use passive voice. Always end answers with a helpful resource. Use these specific industry terms..."
The Verdict: The Gold Standard for businesses.
The Benefit: Once you set this persona, the agent stays in character forever. Whether it is answering a support ticket at 3 AM or chatting with a lead on your website, it speaks exactly how you would speak.
Why "Persona" Matters More Than "Intelligence"
A genius AI that sounds rude or generic will hurt your brand. A moderately smart AI that sounds empathetic, on-brand, and helpful will build loyalty.
When evaluating platforms, ask these 3 questions:
Can I upload my own Brand Guidelines? (AiSentr: Yes)
Does the voice persist across all channels (Slack, Web, WhatsApp)? (AiSentr: Yes)\
Can I tweak the voice instantly without code? (AiSentr: Yes)
Conclusion: Don't Settle for "Robot Voice"
Your brand voice is your most valuable asset. It distinguishes you from the competition.
You don't have to choose between "efficient automation" and "human personality." With customizable agent platforms like AiSentr, you can have both. You can build an AI that doesn't just know your business—it sounds like your business.
